摘要： Plant-specific TEOSINTE-BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR1 (TCP) gene family has versatile functions in diverse aspects of plants. However, less research on banana TCPs was done comprehensively. Accordingly, 48 banana TCP genes were characterized on aspects of gene structure, conserved motifs, phylogenetic relationship, and expression patterns. Members of the MaTCP gene family were unevenly distributed among 11 chromosomes and purification selection was the driving force of the MaTCP gene family. Gene duplication analysis indicated that segmental duplication is the major contributor to family expansion. Promoter analysis showed that MaTCPs might be involved in banana growth, development, and abiotic stress responses. Further, the expression of 12 MaTCPs was analyzed by real-time quantitative RT-PCR, and the protein interaction analysis showed that MaPCF10 and MaPCF13 may have an important function in banana fruit development and ripening. These results lay the foundation for further study of the functions of TCP genes in banana.
